Managing a wiki on github like this. The main motivation here is to compare against confluence lack of offline support. Github wikis seem to be just ordinary files that can be cloned and grepped.
# clone
$ git clone git@github.com:karlpokus/github-wiki.wiki.git docs
# search
$ grep -r password docs
$ grep -r mongo.*port --color docs- page hierarchy
- clone and push
- search
- internal links
